SH E ET-M ETAL CAN.

SPECIFICATION forming part of Letters Patent No. 259,774, dated June 20, 1882.

- Application filed April 12, 1882. (No model.)

To all whom it may concern:

Be it known that we, ISAAC PORTER and HARRY, T. PORTER, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and Stateot' Pennsylvania,

tion of nozzle-cap; Fig. 6,-a similar view of nozzle, seamless ring, and cap. Fig. 7 is a broken vertical section of can with improved joint.

Our invention has forits object to provide a perfectlytight joint for cans containing fluids ofvarious kinds, such as oils,-varnishes, turpentine, &c. p

A further object of our invention is to produce a can-joint of such acharacter thatit may be closed without soldering, yet be perfectly tight and secure against the escape of fluids of the kinds indicated.

A still further object of our invention is to provide means whereby a can provided with a nozzle may have a perfectly fluid-tight yet unsoldered joint in its nozzle, the latter being closed by a cap of soft or other metal, which can be readily cut out, so to leave said nozzle open for pouring purposes and for the reception of a cork or other stopple.

Our improvements consist in the peculiar construction and combination of parts, as hereinafter set forth. 1

Referring to the accompanying drawings, A

' indicates the body of a sheet-metal can, having one of its ends, a, formed with a central opening, a, in which is fitted a nozzle, B, secured in place by soldering. Said body A and nozzle B in themselvesare' formed in the usual manner, with vertical seams closed, as customarS, by soldering. To theupper edgejfthe nozzle is soldered a seamless metallic ring,

0, formed with a shoulder, a, and a flange, 0'. The part 0 below the shoulder or offset 0, enters the nozzle B, and is soldered thereto, said shoulder resting on the upper edge of said nozzle.

D-represents a cap of soft or other metal, which closes the nozzle. Said cap is made in one piece, consisting of the plate or disk d, with rim (1. Said rim is formed with a horizontal annular flange, d which is supported by the nozzle-shoulder o. Between said flange d and shoulder c is a rubber gasket or equivalent elastic packing-ring, a. The parts being in place, the flange o is turned down over the flange d, sutficient pressure being exerted in the act of closure to compress the gasket be-' 6 5 tween the flanges, and thus form a perfectly fluidtight join When it is desired to open the can, a knife or other suitable tool is caused to penetrate the cap D at the junction of the disk and 7e flange or corner d cutting said disk clear out and leaving the rim cl, which then remains as a smooth and seamless lining for the nozzle. The fluid which was placed in the can before closing the latter may now be poured out to any extent desired, and afterward, if expedient, a cork or other stopple maybe inserted in v the nozzle to closeit up.

The cap need not necessarily be. a sunken one fitting in the nozzle, as already described, but by reversing it may be elevated abovev the nozzle, and under some circumstances thecap may consist merely of a flat disk with its edges resting on the shoulder of the ring 0.

The method of construction described and shown may be applied to cans without nozzles as well as to those with nozzles, as we have shown in Fig. 7, where E represents a can-body with seamless ring or rim F, having ofi'set f and flange f, G being the cap or top 0 with flange g, and H the gasket, and our invention includes'this application of the improved joint, as well as that first. described.

. What we claim as our invention is as follows:

1. The combination, with body A, of nozzle B, seamless ring 0, soldered thereto and havin g internal shoulder, c, and flange c, soft-metal cap D, and gasket or packing-ring e, the sev- In testimony that we claim the foregoing we eral partsbeing constructed andcombined subhave hereunto set our hands this 6th day of 10 stantially as shown and described.
